Answer:

Domain of f(x) = 2/7x - 2: (-∞, ∞)

Range of f(x) = 2/7x - 2: (-∞, ∞)

Domain of f(x) = |x + 3| - 1: (-∞, ∞)

Range of f(x) = |x + 3| - 1: [-1, ∞)

Domain of f(x) = -5x + 4: (-∞, ∞)

Range of f(x) = -5x + 4: (-∞, ∞)

Step-by-step explanation:

We can use a graphing calculator to find the graphs.

Domain is the set of all x-values that can be inputted into function <em>x</em>.

Range is the set of all y-values that can be outputted from function <em>x</em>.

Answer:

x = $\sqrt{2}$ ; y = 2

Step-by-step explanation:

You have a 45 -45 - 90 triangle. There are two things to know"

1. The hypothenuse = leg × $\sqrt{2}$

2. The legs are equal.

The hypothenuse is opposite the right angle that is "y" in this problem.

Hypothenuse = leg × $\sqrt{2}$

= $\sqrt{2} \sqrt{2} = \sqrt{4} = 2$

The legs are =

Therefore x = $\sqrt{2}$

Your bank balance is $102.35 and you've just made purchases for $20, $33.33, and $52.80. You then make deposits of $25 and $24.7

Dafna11 [192]

It is A because when you add the amount of your purchases and you subtract it from 102.35. You get a negative number. Then you add that negative number to 25 and 24.75.

Evaluate 7 + (-3x^2) for x = 0. 4

Goshia [24]

Step-by-step explanation:

By substituting x = 0.4 in equation 7 + (-3x^2)

= 7 - 3 (0.4)^2

First solving o.4^2 as per the rule of BODMAS

= 7- 3 (0.16)

Now multiplying -3 with 0.16

= 7 - 0.48

= 6.52 THIS IS THE ANSWER

How many complex roots does the equation below have? X^6+x^3+1=0

gladu [14]

If you find the discriminant it will tell you the number and types of roots. The discriminant is the value b^2 -4ac.
a = 1
b = 1
c = 1
1^2 - 4*1*1
1-4 = -3
Since this is a negative number there will be 2 complex roots.

If you know the area and the base of a triangle, how can you find the height?

Y_Kistochka [10]

Answer: do your values into the equation A=1/2bh and do the math. First multiply the base (b) by 1/2, then divide the area (A) by the product. The resulting value will be the height of your triangle!
